MAGAZINE FOR WEFT-REPLENISHING LOOMS.

Specification of Letters Patent.

Patented June 25, 1918.

Application filed September 25, 1915. Serial No. 52,709.

To all whom it may concern Be it known that we, RANDOLPH CROMPTON and-WILLIAM E. WoonMAN, both citizens of the United States, and residents, respectively, of Chatham and Worcester, in the counties, respectively, of Barnstable and Worcester and State of Massachusetts, have invented an Improvement in Magazines for Weft-Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to magazines for weft replenishing looms, and particularly to improvements in subsidiary magazines for such looms.

In order that the principle of the invention may be readily understood, we have disclosed a single embodiment thereof in the accompanying drawings, wherein Figure 1 is a view, partly in side elevation and partly in vertical section. of a subsidiary magazine embodying our invention;

Fig. 2 is a view, partially in end elevation and partially in horizontal section, of a master magazine for weft replenishing looms having a plurality of subsidiary magazines constructed in accordance with our invention;

Fig. 3 is a view, partially in end elevation and partially in horizontal section, representing other portions of the master magazine;

Fig. 4 is a detail in vertical section of a portion of one of the subsidiary magazines;

Fig. 5 is a vertical section upon the line 5-5 of Fig. 1 and looking toward the left in said figure;

Fig. 6 is a detail in side elevation of the tip of one of the bobbins and the support therefor;

Fig. 7 is a vertical section on the line 77 of Fig. 1; and

Fig. 8 is an end elevation of the threadreceiving spindle of one of the subsidiary magazines.

This invention in certain aspects thereof is an improvement upon the construction disclosed in the patent to Randolph Crompton, No. 1,142,938, dated June 15, 1915.

Referring more particularly to the drawings, we have in Figs. 2 and 3 represented a substantially circular disk-like member 1, which is preferably similar to the corresponding part in said patent. The said member 1 is preferably mounted at the right hand end of the loom and upon the framing 2 thereof; The said member 1 is fixedlymounted upon the shaft 3 in any suitable manner and preferably as shown in said patout. The shaft is preferably provided with an operating cam indicated at 4, in dotted lines and with co-acting members or parts for the operation of the subsidiary magazine. Preferably mounted as disclosed in said patent isa star wheel 5 and a hub 6 provided with a series of radial sockets mally supported in their inner positions by means of a spring 9 herein shown as a coil spring circular in form and the ends of which may be hooked together. so as to engage with suitable studs or pins 10 upon said castings 8. As set forth fully in said patent, the subsidiary magazines are periodically moved radially downward into 00- operate relation with the shuttle in the shuttle box.

Each of said subsidiary magazine cast-.

ings is provided wit-h a member 11 constituting a support for the bases of a series of bobbins or other suitable weft carriers indi cated at 12, and herein shown as four in number. These weft carriers correspond in color or other distinguishing characteristics with the filling in the several shuttles. The member 11 is herein represented as having the form of a cross, and the tip ends of the bobbins 12 are suitably supported in a correspondingly shaped cross member 13 shown most clearly in Fig. 5, thereby to support the bobbins with suitable spring pressure and shaped as indicated so s frictionally to support the tips of the bobbins.

Extending through each casting 8 is a shaft 14 having a suitable bearing therein and herein shown as threaded at 15 to receive nuts 16, 17 whereby the tip holding member 13 is held in position. Fast upon said shaft 14 is a pinion 18 which as shown most clearly in Fig. 4:, is provided with a shallow" socket 19 adapted to receive the curved or rounded end of a pin or plunger 20 which is normally pressed toward said pinion by a coiled spring 21 seated in a socket 22 in the casting 8.

Each of said gears 18 is of the general construction disclosed in said patent and they cooperate with a rack 23 formed or provided upon a swinging segment 24: similar. to that shown in said patent and preferably similarly operated.

In the operation of the replenishing mechanism, it is important that in all the subsidiary magazines the colors be correspondingly positioned prior to the engagement of each subsidiary magazine with the oscillatory rack 28. When the, subsidiary magazines are replenished, it frequently occurs that the colors in the several magazines do not occupy corresponding positions and that the gears thereof are so turned that when replenishment occurs, the several weft carriers' are not properly positioned. In order to permit the 100m attendant manually .to position each subsidiary magazine prior to its engagement with the rack 23, we have provided the pin or plunger 20 whereby the attendant may grasp a portion of each subsidiary magazine and turn it until the said pin or plunger 20 enters the socket 19. The loom attendant, hearing the resulting click, or from the feel of the parts, will know that thebobbins of such subsidiary magazine are properly positioned. In this manner each of the subsidiary magazines is properly positioned, and when each in turn engages the oscillatory rack 23, the latter will rotate the subsidiary magazine to the Proper extent, as setforth in my patent, thus disengaging and, if the movement of the parts requires it, again engaging the plunger 20 with the socket 19. The construction of parts is such that plunger 20 may be disengaged and again engaged a number of times by the rack23 before such subsidiary magazine, is finally moved out of operative position with said rack.

We have herein represented the shaft 1% as having an enlarged outer end 25 herein shown as of conical form at 26' and. terminating in a head 27 preferably cross slitted as indicated at 28, 29. The said cross slits 28, 29. are preferably continued along the conical surface of the shaft, one of the said 'continuations' being indicated at 30 in Fig.

1. that form of our invention herein shown, four slits 30 are provided, spaced apart ninety degrees circlnnferentially of the shaft portion 26. .1 V

The yarns or threads are drawn from the several bobbins, two of them being indicated at 31' in Fig. 1. The said threads are passed to the head 27 and enter the appropriate slit 28 or 29 therein and after passing therethrough emerge therefrom and are wrapped spirally about the conical portions 26 of the shaft 14:, as indicated at 32 in Fig. 1, thus holdingthe thread ends while the. bobbins are supported in the subsidiary magazine. In Order to permit the ready removal of the wrapped portions of the threads, the slit continuations 30 are provided along which a knife may be drawn, thereby severing the threads.

In order to prevent breaking of the threads that eXtend from the bobbins across the ends of the tip supporting member 13, we preferably provide upon each arm of said member 13' a Wire 33, herein shown as of one piece and bent upon itselfas shown so as to embrace or be Wrapped about the arms of the member 13 and to provide a guide portion 34: along which the thread may extend and which offers no sharp edge to the thread and therefore will not break the same. While instead of the wire 83 any other suitable means may be provided, the constructionshown is simple and effectively serves the intended purpose.

The operation of the subsidiary magazines is in general that disclosed in the said patent, and it is unnecessary to set forth the same in detail.

The employment of the, pin or plunger 20 for each subsidiary magazine permits in a simple manner the proper positioning manually of the several bobbins of each magazine prior to the engagement of each pinion 18 with the rack 23.

Having thus described one illustrative embodiment of our invention, we desire. it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.
